Superior sagittal sinusThe largest of the sinuses. It takes most of the blood from the upper surface of the cerebrum.
Inferior sagittal sinusIt drains into the straight sinus.
Great cerebral veinA deep vein of the cerebrum that leads to the straight sinus. It is also called the vein of Galen.
Straight sinusIt takes blood from the great cerebral vein. It leads to a transverse sinus.
Transverse sinusOne on each side. It drains the sagittal, straight and occipital sinuses and leads to the sigmoid sinus.
Occipital sinusA small sinus of the occipital region. It leads up to the transverse sinuses.
Sigmoid sinusIt takes blood from the transverse sinus. It leads through the jugular foramen into the internal jugular vein.
Cavernous sinusIt takes blood from cerebral veins and the eye socket. It leads to the petrosal sinuses.
Face and scalp 3
Superficial temporal veinIt drains the temple and joins the maxillary vein behind the jaw. Their blood goes on to the external jugular vein.
Maxillary veinIt drains the region of the upper jaw. It joins the superficial temporal vein.
Facial veinIt begins beside the root of the nose. It crosses the lower jaw and drains into the internal jugular vein.
Neck 5
External jugular veinIt drains the outer parts of the head and the scalp. It empties into the subclavian vein.
Internal jugular veinIt carries blood from the brain down the neck. It runs beside the common carotid artery, then joins the subclavian vein.
Vertebral veinIt passes down through openings in the sides of the neck vertebrae. It flows into the brachiocephalic vein.
Subclavian veinIt takes in the external jugular vein. It joins the internal jugular vein.
Brachiocephalic veinIt forms where the internal jugular and subclavian veins join. The two brachiocephalic veins join to form the superior vena cava.

How it works
Two side views, face to the left. The first opens the skull to show the sinuses that drain the brain. The second shows the veins of the face and neck down to the collarbone.

Follow the blood out of the head
Inside the skull, blood from the brain collects in the sinuses: the superior sagittal sinus along the top, then the inferior sagittal sinus and the great cerebral vein into the straight sinus, then the transverse and sigmoid sinuses, which lead out of the skull into the internal jugular vein. Outside, the superficial temporal and maxillary veins lead to the external jugular vein, and the facial vein to the internal jugular. The three neck veins are drawn spread apart so each can be tapped.
The sinuses are channels between the layers of the dura mater, the brain's outer covering. Unlike veins, they have no muscle in their walls.
Questions and answers
What are the main veins of the head and neck?
The internal jugular vein, which drains the brain and takes in the facial vein; the external jugular vein, which drains the scalp and the outer parts of the head; and the vertebral vein, which runs down through the neck bones.
What is the difference between the internal and external jugular veins?
The internal jugular vein starts at the base of the skull, carries the blood from the brain, and joins the subclavian vein to form the brachiocephalic vein. The external jugular vein drains the outer parts of the head and empties into the subclavian vein.
What are the dural venous sinuses?
Channels between the layers of the dura mater that collect blood from the brain. The main ones are the superior and inferior sagittal sinuses, the straight sinus, the transverse and sigmoid sinuses and the cavernous sinus.
Where do the veins of the head and neck drain?
Into the brachiocephalic veins at the root of the neck, by way of the internal jugular, external jugular, subclavian and vertebral veins. The two brachiocephalic veins join to form the superior vena cava.
